  • Patent number: 6336888
    Abstract: A vehicular transmission comprises an engine E, a continuously variable transmission CVT and a starting clutch 5. The driving force from the engine E is conveyed through the continuously variable transmission CVT with a speed change to a countershaft 2, and the starting clutch 5 is used to convey this driving force from the countershaft 2 to wheels of a vehicle. The continuously variable transmission CVT is hydraulically controlled by a control valve CV which receives control signals through a line 35 from an electrical control unit ECU. When the temperature of the oil used for engaging and disengaging the starting clutch 5 is equal to or higher than a predetermined temperature, the transmission allows the engine E to stop operating. This control to terminate the operation of the engine is an idling elimination control and is achieved by terminating the fuel supply to the engine and by maintaining the resulting condition of non-fuel supply while the vehicle is being decelerated and brought into a halt.

  • Patent number: 6336657
    Abstract: A seat-occupant restraining apparatus is provided which includes a bag, accommodated in a shoulder belt, for restraining a seat occupant in a seat, and when a vehicle collides, expands the bag with a high-pressure gas produced by an inflator. A relief valve, which opens according to an increase in the internal pressure of the bag, is provided in a gas passage for supplying the high-pressure gas from the inflator to the bag. If the bag is completely expanded by the high-pressure gas from the inflator and the internal pressure of the bag reaches an appropriate value, the relief valve opens and discharges an extra high-pressure gas from the bag, whereby the internal pressure of the bag can be controlled to the appropriate value without causing variations. According to the above-described constriction, it is possible to realize a stable air vent function superior to that of a vent hole, without providing a vent hole in the bag of an air belt assembly.

  • Patent number: 6334925
    Abstract: The present invention relates to a method for bonding together two disc substrates, at least one disc substrate having a UV transmissive-visible light reflective information recording layer provided on a UV transmission base. In this method, the disc substrates are bonded together, so that the information recording layer of one disc substrate faces the other disc substrate, by employing UV irradiation to cure a UV curable composition used as a bonding agent. In the case of the present invention, to cure the bonding agent, UV is irradiated in a single or repeating flash so as not to impair the information recording layer. As a result, the bonding agent can be cured in a shorter period of time with less energy consumed as compared to the conventional method of using conditions irradiation of UV light to cure a UV curable composition used as a bonding agent. Accordingly, the present method enables a product disc to be obtained in a shorter time, with less energy used, so that productivity (i.e.
